Hans Christian Andersen (1805-1875). Danish writer whose fairy tales — The Little Mermaid, The Ugly Duckling, The Emperor's New Clothes, The Snow Queen — became foundational to European literature and have been translated into more than 125 languages. Andersen's biographical record contains many of the features contemporary clinical literature recognizes as autistic-coded: extreme social difficulties, obsessive routines, sensory sensitivities (he traveled with a coil of rope to escape hotel fires and a note pinned to his clothing reading "I am not really dead" in case he was buried alive), social naivety throughout his adult life, and a cognitive style that mapped easily onto the perspective of children and outsiders. The Ugly Duckling is widely read as autobiographical. His cognitive signature is the discovery specialty's perceptual outsider position translated into literature that the integration culture could absorb because it was framed as children's fantasy. The integration partner was the Danish and German publishing infrastructure that received and circulated his work. (Speculative case; Andersen lived in the nineteenth century. The behavioral record is unusually well-documented.)
